Three problems related to radiator have been reported for the 1999 Chevrolet Monte Carlo. The most recently reported issues are listed below.
We were preparing to take a long trip and took our 1999 Monte Carlo into our mechanic for a pre-trip once-over. He just called and informed us that the radiator was almost empty and that there is a leak in the intake manifold gasket, it can (and will) be fixed for a cost of $750. 00. Our mechanic has a small shop and he has fixed the same problem at least once a month on gm products with a 3. 1 liter engine, he just had a Buick last week with the identical problem. Doesn't anybody else see this as an issue that gm needs to take some kind of action about?? we would have been livid if this car had broken down in the desert on the way to las vegas!! we were really happy with this vehicle, but now plan to sell it and we will be looking for something witout a recurring problem of this magnitude!.
Intake manifold gasket leak, 1999 chev Monte Carlo. Notice low radiator coolant at about 50m, problem got worse and found that dexcool coolant was leanking to the outside of the engine from the intake manifold.
Vehicle has a 3. 1l v6 engine that was leaking coolant as a result of a cracked intake manifold gasket. I was told by my mechanic that they are replacing this gasket on at least one vehicle a week. And they are just a small shop. The first problem I noticed with this vehicle was a slow leak in the cooling system. This occurred in the summer of 2002. Later in the year, I noticed coolant on the garage floor and thought perhaps the radiator was leaking. When I took the car in to be repaired on December 16, 2002, it had 51,223 miles on it. The cost of just repairing the intake manifold gasket was $482. 21 plus tax, for a total of $512. 35.
